See my above or well below post about recovered PR bullet from cow elk. Excellant accuracy out of my Austin Hellecks. My TC Black Diamond does not seem to like them but I think I got a bad gun because I have not found anything it does like. Groups with open sights as required by law here in Washington are a ragged hole at 50Yds iif I do my part. Shot four or five deer with them and only ever recovered on from a deer it went through a shoulder and still looked good. Got the one back from the elk this year because they are so much tougher. I like heavier bullets and am shooting the 340gr.
